'We can no longer be silent': Pakistan will pay for harbouring terrorists, warns Donald Trump

US President Donald Trump on Monday laid out a tougher approach to US policy toward Pakistan, while unveiling his updated Afghanistan policy. 

Trump's speech came as the president tries to regain momentum after he was engulfed in controversy for saying both sides were to blame for violence between white supremacists and counter-protesters in Charlottesville, Virginia, earlier this month.

Trump, in a prime-time televised address at a military base near Washington, warned he could reduce security assistance for Pakistan unless the nuclear-armed nation cooperates more in preventing militants from using safe havens on its soil.

"We can no longer be silent about Pakistan’s safe havens," Trump said. 

"Pakistan has much to gain from partnering with our effort in Afghanistan. It has much to lose by continuing to harbor terrorists."

Trump also said the United States wanted India to help more with Afghanistan, especially in the areas of economic assistance and development.

He made clear his patience had limits in support of the Afghanistan government, saying Kabul needed to increase its cooperation in order to justify a continued American commitment.
